Guilherme Mascarenhas: The Blitz Bandit
Meet Guilherme Mascarenhas, or as the internet often knows him, gui456789 — a chess player whose blitz games are as unpredictable as a cat walking on a keyboard. With a peak blitz rating soaring to 527 in April 2025, Guilherme has shown flashes of brilliance alongside some intensely humbling moments (his minimum rating once sank to a mere 157, because hey, every prodigy has an off day).
Known for his tactical warfare and psychological tenacity, Guilherme boasts a 60.4% comeback rate—perfect for those nail-biting scenarios when the board looks bleak but hey, never count him out. He’s also scientifically inclined to do better at odd hours; his best play time is apparently around 3 a.m. when the world sleeps and Guilherme turns into a strategic maestro.
Playing Style & Preferences
-
Opening Arsenal: Guilherme’s blitz favorite is the King’s Pawn Opening with a win rate hovering around 41%, but if he’s feeling spicy, he’ll employ the King’s Pawn Opening Kings Knight Variation, where he scores nearly 59% wins. The Italian Game Knight Attack is his surprise weapon with an impressive 75% success rate in blitz.
-
Endgame & Resignations: He has a penchant for early resignations at about 22%, which maybe means he knows when to cut losses or he’s the kind of player who hates lingering in a bad position. Despite that, he loves engaging in endgames, appearing in one-third of his bouts.
-
White vs. Black: Slightly better with the white pieces (46% wins) than black (41%), proving that having the first move still counts for something — or at least helps Guilherme’s style.
Notable Stats & Stories
Guilherme has played an impressive 114 blitz games in April 2025 alone, winning 48 of them. His current winning streak stands at a modest but proud 1, after a past rollercoaster of a 6-game winning streak (and a soul-crushing 9-game losing streak to keep things balanced). When he beats opponents like j4luk or imsotrashbroo, the victory is absolute—a 100% win rate!
He recently executed a beautiful checkmate in under 12 moves in a blitz game on May 30, 2025, showcasing his tactical wit and a keen sense for spotting mating nets before breakfast. Guilherme is known to wield the Nimzowitsch Defense Declined with style and sometimes recur to tricky gambits like the Englund Gambit—because why not spice things up?
The Personality Behind the Pieces
Chess for Guilherme is a blend of fun, frustration, and fanaticism. With a tilt factor rated at 9 (high, but hey, nobody’s perfect), he wears his heart on his sleeve and often battles the clock almost as fiercely as his opponents. A loyal night owl, he dominates early morning hours with a win rate peaking at 70% around 3 am, when the stars align and blunders magically transform into brilliant moves.
Whether you call him Guilherme or just gui456789, expect a player who embraces both the fools and the geniuses within the 64 squares — and don’t be surprised if he’s plotting his next comeback while you read this.
